Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

科学领域:

  • 人与计算机的交互
  • 网络可访问性研究 网络可访问性研究
  • 数字广告数字广告

背景情况:

  • 网络广告很普遍,但主要设计用于视觉交互.
  • 广告对盲人用户的影响依赖屏幕阅读器是研究不足的.
  • 现有的关于非视觉网络互动的研究忽视了广告内容所带来的具体挑战.

研究的目的:

  • 调查情境欺骗性广告如何影响盲人用户的网页浏览体验.
  • 开发和评估用于识别上下文欺骗性广告的自动化方法.
  • 通过解决与广告相关的障碍,提高视力受损用户的网络可访问性.

主要方法:

  • 对18名盲人参与者进行了采访研究,以了解他们对网络广告的体验.
  • 开发了一种采用手工制作和自动提取特征的多模式方法的检测模型.
  • 在测试数据集和现实世界网站上评估模型的性能.

主要成果:

  • 盲人用户报告说,他们经常被广告欺骗,这些广告与网站内容无融合.
  • 开发的算法实现了高检测准确性,在测试数据集上F1得分为0.86,在实时网站上为0.88.
  • 识别了广告屏蔽器的局限性,特别是它们对内部注入广告和网站访问限制的无效性.

结论:

  • 情境欺骗性广告对盲目的网络用户构成重大挑战.
  • 拟议的检测算法为识别和潜在地减轻欺骗性广告提供了可行的解决方案.
  • 需要进一步的研究和开发,以提高视力障碍者对网络广告的可访问性.
